Figure 1
4.Install the unit a little slanted so the back is slightly lower than the front (about 10~15mm). This will help force condensed water to the outside. 5.Install the unit from the bottom about 75~150cm above the floor level.
Installation Check The setting conditions must be checked prior to initial starting. The following items are especially important checking points when the installation is finished. 1. Grounding wire (Green or Green and Yellow) is provided in the power cord. The green wire must be grounded. 2. Connect to a single-outlet 15A circuit. (or 20A circuit for Electric Heater Model) 3. To avoid vibration or noise, make sure the air conditioner is installed securely. 4 Avoid placing furniture or draperies in front of the air inlet and outlet.
How to Secure the Drain Pipe In humid weather, excess water may cause the BASE PAN to overflow. To drain the water, remove the DRAIN CAP and secure the DRAIN PIPE to the rear hole of the BASE PAN. Press the drain pipe into the hole by pushing down and away from Drain pipe the fins to avoid injury.
Drain cap
Optional 1. Install the drain pan over the corner of the cabinet where you removed the CABINET plug with 4 (or 2) screws. 2. Connect the drain hose to the outlet located at the bottom of the drain pan. You can purchase the drain hose or tubing locally to satisfy your particular DRAIN PAN needs. (Drain hose is not supplied). 3. Select the most appropriate connection from among the following figures (by considering the hole of the unit) to fit drain pan to your own unit.

Disassembly NOTICE
— Replacement of the refrigeration cycle. 1. When replacing the refrigeration cycle, be sure to Discharge the refrigerant system using a FreonTM recovery System. If there is no valve to attach the recovery system, install one (such as a WATCO A-1) before venting the FreonTM. Leave the valve in place after servicing the system. 2. After discharging the unit completely, remove the desired component, and unbraze the pinch-off tubes. 3. Braze service valves into the pinch-off tube ports, leaving the valves open. 4. Braze the pinch-off tubes with Service valves. 5. Evacuate as follows. 1) Connect the vacuum pump, as illustrated figure 33A. 2) Start the vacuum pump, slowly open manifold valves A and B with two full turns counterclockwise and leave the valves open. The vacuum pump is now pulling through valves A and B up to valve C by means of the manifold and entire system.
CAUTION: If high vacuum equipment is used, just crack valves A and B for a few minutes, then open slowly with the two full turns counterclockwise. This will keep oil from foaming and being drawn into the vacuum pump.
6. Recharge as follows : 1) Refrigeration cycle systems are charged from the High-side. If the total charge cannot be put in the High-side, the balance will be put in the suction line through the access valve which you installed as the system was opened. 2) Connect the charging cylinder as shown in figure 33B. With valve C open, discharge the hose at the manifold connection. 3) Open valve A and allow the proper charge to enter the system. Valve B is still closed. 4) If more charge is required, the high-side will not take it. Close valve A. 5) With the unit running, open valve B and add the balance of the charge. a. Do not add the liquid refrigerant to the Lowside. b. Watch the Low-side gauge; allow pressure to rise to 30 lbs (0.2Mp). c. Turn off valve B and allow pressure to drop. d. Repeat steps b. and c. until the balance of the charge is in the system. 6) When satisfied the unit is operating correctly, use the pinch-off tool with the unit still running and clamp on to the pinch-off tube. Using a tube cutter, cut the pinch-off tube about 2 inches from the pinch-off tool. Use sil-fos brazing rod and braze pinch-off tube closed. Turn off the unit, allow it to set for a while, and then test the leakage of the pinch-off connection.
3) Operate the vacuum pump vaccum for 20 to 30 minutes, until 600 microns of vaccum is obtained. Close valves A and B, and observe vacuum gauge for a few minutes. A rise in pressure would indicate a possible leak or moisture remaining in the system. With valves A and B closed, stop the vacuum pump. 4) Remove the hose from the vacuum pump and place it on the charging cylinder. See figure 33B. Open valve C. Discharge the line at the manifold connection. 5) The system is now ready for final charging.
